Hiking in Gwynedd, Wales takes you from the high ridges of Yr Wyddfa via the Rhyd Ddu Path to the stone-backed ascent of Cader Idris on the Pony Path. Around Beddgelert and Croesor, old quarry country opens into dramatic valleys, while the Mawddach Trail rolls beside the estuary toward Barmouth. Aber Falls adds a shorter walk with a strong sense of Eryri’s raw, weather-cut character.
